How times change. The USA was once willing to provide political asylum in its Budapest embassy for 15 years:
The memorial plaque reads:
"The Government of the United States of America gave shelter to Cardinal Joseph Mindszenty in this building between November 4, 1956 - September 28, 1971"
"Az Amerikai Egyesült Államok kormánya ebben az épületben adott menedéket Mindszenty József bíborosnak 1956. november 4. – 1971. szeptember 28. között"
In my view, the Government of Great Britain has suffered enormous reputational damage for even considering breaching diplomatic protocol. Much of the rest of the world will tell itself that the mask slipped for a moment and showed the ugly face of our ruthless, law-despising power elite. Real tyrants like Putin will be able to say "tu quoque" when justifying their own short way with dissenters.
